摘要：
We have developed a semitransparent cathode for the top emission organic light-emitting devices using a Sr/Ag double layer prepared by the thermal evaporation technique. The Sr (8-10 nm)/Ag (10 nm)cathode shows the transmittance of 55-76% in the visible spectral region and the sheet resistance of about 12 Omega/(-). The underlying Sr layer affects the growing characteristics of Ag layer, resulting in high optical transparency. The bis[2-(2'-benzothienyl)-pyridinato-N,C3+]iridium(acetylacetonate) doped top emission electro-phosphorescent device with a Sr/Ag semitransparent cathode has been fabricated and studied.
